They are not updated in any particular order. When the update is scheduled all affected switches start the firmware download. They then wait for up to 20 minutes for other switches to finish their download, and then reboot and do the upgrade. https://documentation.meraki.com/Architectures_and_Best_Practices/Cisco_Meraki_Best_Practice_Design/Best_Practices_for_Meraki_Firmware#Best_Practice_for_MS_Firmware You can use the staged switch upgrade tool to do switches in a particular order. https://documentation.meraki.com/MS/Other_Topics/Staged_Upgrades_for_Meraki_Switches Note if you upgrade any switch in a physical stack all switches will upgrade and reboot.

@PhilipDAth is correct and I have tried it, works great. With MS11 firmware you can run dual power supplies on your MS350 in combined mode to double the PoE budget. You can go to Switch > Configure > Switch Settings and set a default for all capable switches in the network to default to redundant power or combined power. And then you can set custom lists of switches that will always use redundant power and/or always use combined power to override any defaults.

Unfortunately there are no deployment guides for the vMX yet other than the deployment instructions here: https://documentation.meraki.com/MX-Z/Installation_Guides/vMX100_Setup_Guide_for_Microsoft_Azure & https://documentation.meraki.com/MX-Z/Installation_Guides/vMX100_Setup_Guide_for_Amazon_AWS As @kevinl mentioned, you can deploy multiple vMX appliances to scale the VPN connections.

I don't, but I suppose it might be possible to discover by forcing an update and capturing with Wireshark. Do you also have MX? It would simplify packet capture. I suppose you have capped/expensive internet service?

Hi Similar devices in a single network update at the same time. Also I believe the firmware size is in MBs. However I shall reiterate the upgrade download is negligible. I have not experienced heavy downloads atleast for MRs.
